WAVE-POWER.

SPECIFICATION forming part of Letters Patent No.p281,7370, dated July17, 1883.

Application filed March 13, 1883. (No mom-1. v

.T 0 @ZZ whom it puny concern:

Be it known that I, WILLIAM E. JoRY, of the city and county of SanFrancisco, State of California, have invented an Improved Wave- Power 5and I hereby declare the following to be a full, clear, andeXactdescription thereof.

lVIy invention relates to that class of devices specially adapted to beaffected by the waves, and commonly known as wave-powers.

It consists in a float having vertical screws connected with the mainshaft by gearing, which transmits the vertical movement of said screwsin the manner I shall hereinafter particularly describe.

The object of my invention is to provide a simple and effective meansfor utilizing the power of the waves or tides.

Referring to the accompanying drawings, Figure l is a side elevation ofmy device. Fig. 2 is a plan ofthe ratchets H, gear I, and pawl fi. Fig.3 is a detail section of same on screw.

A is a wharf or other suitable foundation secured in the water. Underit, and between it and the supports or piles, is a large float, B, uponthe water.

C C are the standards, one at each end and one in the middle, connectedloosely with the oat by a ball-and-socket joint, designated by c,whereby the float may adapt itself to the changing surface of the waterwithout. affecting the perpendicularity of the standards. Thesestandards extend up through the wharf loosely, and have vertical screwsD secured toy their tops. .y

E E are side supports or frame-work, having projecting arms a a, betweenand in the ends of which is mounted the'driving-shaft F. Arms e extendinwardly and serve as guides for the vertical end screws, D, and abracket,

G, `secured to the wharf, the central screw.

Mounted upon the screws D are ratchets H. These are loose upon thescrews, and have studs h, traveling in the threads of the screw, wherebythe vertical movement vof the screws will turn the ratchets, Fig. 3.

Mounted loosely upon the screws are gears I, having pawls z', held toplace by springs i. These pawls are adapted to be engaged by theratchets when turning in one direction, but

serves as a guide for i not in the. other, as I shall explain. The endgears, I, `mesh with pinions J on the drivingshaft. The central gearmeshes with a pinion, K, on a supplementary shaft, L, the top of whichis provided with -a gear, lVI, meshing with a pinion, J', on, thedriVingshaft. The threads of the end screws have an opposite direction,one being'right hand and the other left hand, in-order to drive theshaft in the same direction. The center one has its threadscorresponding to one of the ends for a similar purpose. The pawls t'ofthe end gears, I, are so arranged that when the screws move up, theirratchets H will engage them, 'and so turn the gears; but when the screwsmove down,

movement results. rIhe pawl of the center gear is arranged `inan'opposite manner, so that it is engaged by the ratchet only when thecentral screw -moves down.

The operation of the device is as follows: A wave striking under one endlof the float elevates that end and depresses the other. One end screwis elevated and transmits motion to the driving-shaft, while the otheris lowered and does not operate, and vice versa. The oat, by beingconnected with ball-andp socket j oint, may thus move freely. Alldownward movement of the float is transmitted through the central screw.The screws are made long enough to allow for the rise and fall of thetide and still operate. Any movement of the oat is thus transmitted tothe driving-shaft.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In awave-power, the float B, the standards C, connected looselytherewith, and the vertical screws D, on the standards, in combinationwith the ratchets H, loosely mounted on the screws, and having studs h,traveling in .their threads, the driving-shaft F, and intermediate gearsfor transmitting the motion of the ratchets to the shaft, substantiallyas herein described.

the ratchets do not engage the pawls, and no 2. In a wave-power, theiioat B, the standards C, connected loosely therewith, and the verticalscrews D on the standards, in combination with the loose ratchets H, onsaid screws,

having studs h, traveling in their threads, the gears I, loose on saidscrews, and having pawls i, engaged by the ratehets, and thedrivingshaft F, having gears engaging with gears I, substantially asherein described.

3. rI he iloat B, having loose end standards, C, and end screws, D,having threads of different direction, in combination with the ratchctsH,having studs 11traveling in their threads, the loose gears I, havingpawls z', engaged by the ratchets when the screws move up and disengagedwhen they fall, the driving-shaft F, and pinions J, meshing with gearsI, whereby the action of the waves on either end of the loat may betransmitted to the drivingshaft, substantially as herein described.

4. The float B, having a central standard,

C, loosely connected therewith, and the eentral vertical screw, D, onsaid standard, in combination with the ratchet H, having a stud, 71.,traveling in the thread of the screw, the gear I, having a pawl, i,adapted to be engaged by the ratchet when the screw moves down and todisengage when it moves up, the supplementary shaft L, having pinion K,and gear M, and the driving-shaft F, having pinion J, all arranged andoperating substantially as herein described.

In witness whereof I hereunto set my hand.
